An unsuspecting bug bite while I was doing yard work left me with a debilitating neurological disease
A man in Canada has issued an urgent warning after contracting a deadly mosquito-borne illness while doing yard work.
René van den Berg of Ontario was working in his backyard in September when he suspects he was bitten by a mosquito.
By September 20, van den Berg had developed headaches, which eventually became so debilitating that he rushed to the hospital.
A battery of tests, including a CT scan and lumbar puncture, finally revealed viral meningitis, which causes inflammation around the meninges, the protective lining covering the brain and spinal cord.
While most cases involve mild symptoms like fever and headaches and resolve on their own, rare instances can cause vision and hearing loss, along with memory and balance issues.
Doctors found that van den Berg’s meningitis was caused by West Nile virus, a mosquito-borne illness that usually causes no symptoms.
But in one in five patients, the disease can lead to fever, headaches, nausea, diarrhea, joint pain and pain behind the eyes. And in one percent of cases, like van den Berg’s, the virus penetrates the blood-brain barrier and travels to the meninges, causing meningitis and potential paralysis.
Van den Berg noted he was surprised to have been bitten so late in the year.

He told CTV News: ‘I thought mosquitoes would die off at the end of August, when temperatures get colder at night.’
Van den Berg’s illness came on as mosquito-borne illnesses like West Nile surge in the US and Canada even as summer has waned and fall sets in, which experts believe could be due to rising temperatures.
West Nile is the leading mosquito-borne illness in the US, caused by a bite from Culex mosquitoes.
It’s most common in Great Plains states like North Dakota, South Dakota, Nebraska and Colorado, though cities like Los Angeles, Chicago and Dallas-Fort Worth also record high levels due to large populations.
Many of these states have also extended mosquito season due to the increases in mosquito prevalence later in the year.
The latest CDC data shows cases are up 40 percent compared to this time last year, with about 3,500 infections recorded so far this year.
It typically causes around 2,200 severe cases and 180 deaths annually.
West Nile is fatal in about one out of 10 people who go on to develop nervous system infections, or about one in 1,500 people with West Nile.
Older adults, people with weakened immune systems, and those with certain chronic conditions face the highest risk of severe illness due to West Nile.
Even survivors of severe West Nile illness may experience long-lasting complications, including memory problems, chronic fatigue, muscle tremors, or permanent neurological damage.

West Nile virus can be prevented primarily by avoiding mosquito bites. CDC officials recommend using insect repellents that contain the ingredient DEET, wearing long sleeves and pants outside and staying inside between dusk and dawn during the summer.
Van den Berg ended up spending 11 days in the hospital recovering from West Nile and meningitis and is now finishing his recovery at home.
He is now warning others to not to underestimate their risk, even when most cases are mild. ‘Wear mosquito repellent, long sleeves if there’s mosquitos around. Just try to prevent a bite,’ he said.
‘One percent is not as little as you think it is.’
